As a general rule, lactation is com-pleted at the end of a year, but this period is subject to many variations. Asecretion of milk out of all proportion to the demands of the child is knownas polygalactia, and if it persists when the child is not nursing it is termedgalactorrhea (see Part VII). Defective secretion of milk is common in thevery young or the elderly, in the delicate, weak, and cachectic. The obese alsosuffer in this respect, the breasts in such women being subdeveloped. Accordingto Baumm and Illner, there are no true galactogogues, nor can the secretionof milk be modified by the diet; but the amount of milk can be much lessenedby insufficient diet and then brought to the normal by generous regimen. Thecomposition of milk varies more or less in the same woman, and while thegross amount is not affected by diet, the milk may be made richer in fat by

The limits of variability appear to be as follows: Proteids,1.41 to 3.50 (per cent.); fat,. 1.42 to 5.25; sugar, 5.04 to 7.76; ash, 0.16 to0.36. The milk of a primipara is somewhat richer in solids than is that of amultipara. Age alone, within certain limits, is without effect upon the com-position of the milk. The period of lactation exerts ver) little influence, al-though during the first ten days of the puerperium there is a steady declinein the proteid, which thereafter remains constant. Baumm and Illner havemade many studies in connection with feeding nursing mothers. The milkas a w
